This is an update on the Snap-on Brands
Snap-on owns Sioux Tools in NC
They also hold the name Bonney Tools in order to keep the brand alive they market some crowsfeet under that brand.
Take the next discussion with a grain of salt. I was a Snap-on Tools dealer in Cincinnati in the late 1970’s. At the time Mac was headquatered out of Washington Court House Ohio. The rumor was that Matco manufactured tool boxes and distributed air tools out of a large distribution center in Columbus OH, with Mac as their only customer.
Mac discontinued the relationship. Matco had manufacturing and distribution, without a retail outlet. Their solution was to start Matco. Again this was all rumor!
